SPECIFICATION forming part of Letters Patent No. 497,435, dated May 16, 1893.

` Application tiled November 8, 1892. SerialNo. 451.879. (No model.)

To all whom, t may concern,.-

Be it known that I, WILLIAM G. TAYLOR@ citizen of the United States, residing at Hulton, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Fuel-Gas Mixers, of which the following is a specification.

My invention relates to mixers for fuel gas, and my invention consists in constructing the said mixers as fully set forth hereinafter, so as to facilitate adjustment,secureaproper supply of oxygen, and maintain the xed parts in their proper relations, all as fully set forth hereinafter, as illustrated in the accompanying drawings, in whieh- Figure 1 is an external view of a gas mixer embodying my improvements; and, Fig. 2 is a longitudinal section thereof. L

The nozzle or gas tip a2 is connected with and preferably forms a part of a casting which includes a tube, A, having a lower flanged portion a which surrounds the nozzle a2 and an upper hollow cylindrical portion b whichis threaded exteriorly. The nozzle a2 is connected with the flanged portiona of the tube through the medium Vof radiating arms or Wings, l, l, of any suitable number sulicient to hold the parts in relative position and at the same time, to permit the entrance of the air into the lower mouth of the flanged portion. The nozzle a2 is threaded for attachment to the supply pipe.

The threaded end b of the pipe A extends into the threaded end of a pipe d which is adapted to be connected with the burner or with the pipe leading to the burner in any suitable manner, and the said pipe d supports a cone f, which may be of any suitable material as steel, cast iron, porcelain'or other refractory material, and which is supported by wings, 2, 2, extending tothe sides of the tube d, sufficient in number to hold the cone in place and at the same time, permit the passage of the gases along the tube.

It has been found extremely desirable to adj ust the cone f to and from the nozzleaccording to the character of the flow of the gas and to do this with extreme nicety Without permitting the access of air except such as flows into thelower end of the flanged portion a'of the tube A, and in order to secure this result, I support the cone,f by the section d of the mixer and support the nozzle 0.2 by the other section and connect the two sections together, as by the threaded connection, so that one may be adjusted in respect to the other or turned in respect to the other to bring the cone nearer or carry it farther from the nozzle. This connection further enables me to bring the cone into very close proximity to the mouth of the nozzle which is sometimes quite important. It will be seen that Whatever the adjustment .may be, Whether the cone is carried nearer to or farther from the nozzle, by the use of a screw connection between the twotubes A and 61,1 am enabled to secure the desired connection Without permitting the entrance of any air to the tube exceptsuch as flows in at the bottom. y

In order to readily remove the cone f if it should be required either to replace it in consequence of Wear or for other reasons, I prefer to provide it with a screw shank, 3, adapted to a threaded opening in the support, 2, to which it may be screwed and from which it may be detached as desired. The nozzle a2 may also be separate from the support, l, and may be threaded so as to be connected to and detached from the latter, but I prefer to form the nozzle and the tube A in one piece as before described, as it facilitates manufacture and insures absolutely the proper adj ustment of the parts in relation to eachother.

It will be seen that While I am thus enabled to adjust the relations of the nozzle a2 and the cone f, I do not under any circumstances disturb the relation of the nozzle a2 to the flanged portion ctof the tube A, nor the relation of the cone f to the tube d.

Without limiting myself to the precise construction and arrangement of the parts shown, I claim as my invention and desire to secure by Letters Patent-` l. A mixer for fuel gas, comprising 'two tubes, one tube having a cylindrical portion,

a flanged portion and a nozzle, and the other comprising a cylindrical portion and a cone, the tubes being directly but adjustably connected together, so that the relation of the nozzle and cone maybe adjusted Withoutpermitting the access ot' air except through the lower end of the tube; substantially as described.

2. In a mixer for fuel gas, thc combination with a tube, having a cylindrical portion, a Haring portion and a nozzle supported in the Haring portion near the mouth of the latter;

with a tube A having a screw-threaded porof another tube having a cone centrallysupported therein, the two tubes being directly but adjustably connected together to move one within the other; substantially as described.

3. In a mixer for fuel gas, the combination with the tube A having a threaded portion, a

flaring portion and a nozzle; of a tube d having a threaded portion adapted to engage the threaded portion of the tube A, and a cone supported in said tube cl; substantially as described.

4. In a mixer for fuel gas, the combination with the tube having a cylindrical portion, a

flaring portion, and a nozzle supported thereother tube having a cylindrical portion embracing the cylindrical portion of the Iirst tube, and having arms and a cone supported by said arms; substantially as described.

5. In a mixer for fuel gas, the combination tion b, the flanged portion a and nozzle a2 mounted therein; of a tube d havinga screwthreaded portion fitting the portion b and provided With arms 2, and a cone f having a screw-threaded stem fittinga threaded socket 'in said arms; substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.

WILLIAM G. TAYLOR.
